MB85RS2MTYPNF-G-AWE2

Memory IC Overview

The MB85RS2MTYPNF-G-AWE2 is a nonvolatile ferroelectric RAM (FeRAM) integrated circuit manufactured by RAMXEED. It features a memory organization of 262,144 words by 8 bits, providing a total capacity of 2 megabits. The device utilizes a Serial Peripheral Interface (SPI) compatible with modes 0 and 3, supporting a maximum operating frequency of 50 MHz. It operates within a supply voltage range of 1.8 V to 3.6 V and functions across an ambient temperature range of -40°C to +125°C. The component is housed in an 8-pin plastic SOP package.

Memory IC Feature Summary

• High endurance capability allowing up to 10^13 read/write operations per byte without degradation.
• Includes a dedicated special sector region and a unique 64-bit serial number region that retain data stability through multiple reflow soldering cycles.
• Supports deep power down mode for reduced standby current consumption while maintaining system readiness.
• Features hardware write protection mechanisms controlled via status register bits and the WP pin.

Memory IC Applications

• Data logging in high-temperature industrial environments
• Configuration storage requiring frequent updates
• Systems needing battery-free volatile-like performance

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the shipping form, as the AWE2 designation indicates tube packaging. Confirm moisture sensitivity level requirements and floor life constraints prior to assembly. Ensure compatibility with SPI controller timing parameters, particularly regarding clock frequency limits during read operations.

Memory IC Selection Notes

Select this component when high-cycle endurance and fast write speeds are critical compared to flash or EEPROM alternatives. Consider the 8-pin SOP footprint for space-constrained designs. Evaluate the need for the special sector if data retention through reflow is required. Verify interface compatibility with the host microcontroller's SPI capabilities.

Memory IC Part Context

This part belongs to the MB85RS2MTY series of FeRAM devices from RAMXEED, formerly Fujitsu Semiconductor Memory Solutions Limited.
